PASTING ATTACHMENT FOR PAPER-FOLDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 325,023. dated August 25, 1885.

(N0 moth-1.]

To all whmn it may concern.-

Be it known that I, John STONEMETZ, a citizen ot'the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Pasting Attachments for Paper-Folding Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The present invention relates to the class of pasting mechanisms forpaper-folding machines which have a paste-wheel carried by a pivoted arm which is automatically lowered onto and raised from the sheets of paper.

The object of my invention is to provide a pasting mechanism which shall be free from the objections incident to the arrangement of devices heretofore nsed,which Iaecomplish by connecting the pastingwhecl with the operating parts of the paper-folder, so that it will receive a positive motion independent of the sheet of paper passing beneath, and which will be always rotating at the same speed whether the wheel is lowered onto the paper or raised. It follows from this that no part of the pasting mechanism need necessarily touch the paper except the edge of the pastewheel, and, as the latter is always rotating through the medium of positive connections at the same speed as the paper, the pasting is done uniformly and evenly, without the least tendency either to retard or accelerate the speed of the paper. By driving the pastewheel in this manner I am able to adjust and regulate the pasting mechanism so that it will not necessarily rest its whole weight on the paper when lowered, but it can be adjusted so that it will touch it as lightly as desired.

My invention consists of a pasting mechanism for paperfolding machines operating substantially in the manner above indicated, as hereinafter described and claimed.

Figure 1 is a vertical section through a pa per-folding machine, taken parallel withthe first pair of folding-rolls,showing the pasting wheel lowered; and Fig. 2 is an enlarged view of the pasting-wheel, with its supporting-arm and operating meehanismamlthe parts of the folding-machine immediately adjacent thereto, the wheel being in a raised position.

The construction and operation of paperfolding machines is so well understood that only those parts immediately connected with the pasting mechanism will be shown and described.

Port-ions of the frame of a folding-machine are shown at A, and B is one of the first pair of folding-rolls, with portions of some of the carrier-tapes G, which conveythe folded sheet to the second pair of rolls.

D is the lever-arm which carries the pastereceptaele G and the pastingwheel E, the latter rotating through a slot in the bottom of the pastebox. The lever-arm is pivoted to the. frame at d, and its short arm (1 bears against the eanrwhecl F, by means of which the lever and paste-wheel are automatically raised and lowered. The cam-wheel F is mounted on a stud, a, projecting from the folder-frame,and it has the can] fand circumferential gears which mesh with the pinion l1 on the end of the main driving-sliai't H. The mechanism to this extent does not differ in any essential particulars from the pastors-heretofore used.

Beneath the levcr-arn1, and parallel with it, there is a shaft, K, which is supported by the bearings (P, attached to the lever-arm. The paste-wheel E is fastened to one end of this shaft and rotates with it, and at the other end there is a pinion, 7;, which meshes in with a gear, I), on the end of one of the rolls B, the pinion and gear being of such relative sizes as will give the same surfacespced to the roller and paste-wheel.

It will thus be seen that the rotation of the roller causes a corresponding rotation of the adjacent edge of the paste-wheel in the same direction and at the same speed,without the roller and paste-wheel necessarily touching each other. The screw-pin L, carried by a bracket, Z, extending out from the side of the frame, comes immediately behind the short arm d of the lever and in the same vertical plane. By screwing the pin L in the leverarm D is raised, as shown by Fig. 2, and by ICO means of this screw-pinthe short arm (1 of the lever can be held in far enough so as to clear the cam f, in which case the paste-Wheel will be entirely raised from the paper and thrown 5 out of action; or by means of the screw-pin the lever-arm can be adjusted so'that the paste-wheel when in its lowest position will just touch the surface of the sheet of paper beneath it without allowing its entire weight to rest upon it. As the pinion K is placed close to the fulcrum d of thelever-arm, the displacement of the pinion incident to the raising of the lever is not sufficient to interfere with the intermeshing of the pinion with its gear. The extent of this movement is exaggerated in Fig, 2, in order to clearly illustrate the operation of the device.

I also provide another means for regulating the lever by making the cam-wheel F adjus able on its stud. This wheel is held on its stud by the nut f and jam-nut f and the short arm (2 of the lever, bearing against the face of the cam on the inner face of the wheel, holds it out against the fastening-nuts. By

setting the nuts in or out the cam-wheel can be adjusted so that in the lowered position of the lever the paste-wheel will be as close to the roller as desired, or even so that it will not touch the paper when the mechanism is prac- 0 tically thrown out of action; but the adjustment of the cam-wheel is preferably employed to regulate the position of the paste-wheel with respect to the paper and the screw-pin L when it is desired to throw the pasting 5 mechanism out of action.

It will be understood that my invention can be applied in a similar manner to the second pasting device of a sixteen-page folding-machine, and that other intermediate connec- 0 tions between the shaft of the paste-wheel and operating parts of the folder may be employed without departing from the fundamental idea of my invention, the essential feature of which is a positive connection between the pasting- 5 wheel and the roll in connection with which it operates, the same being independent of the paper. For example, a belt could be carried from the paste-wheel shaft around sheaves placed at the fulcrum of the lever down to the folder mechanism, or sprocket-wheels and chain can be employed, or other devices which will readily suggest themselves to a skilled mechanic; and the same result can be secured if the pinion of the paste-wheel shaft does not connect directly with the gear of the foldingroll, but with a gear placed on some main or intermediate shaft of the folder, which is connected with the folding-roll beneath the pastewheel by proper mechanism; but I consider that the mechanism above described best ac complishes the desired result.

I am aware that Letters Patent No. 227,599 were granted to S. D. Tucker on May 11, 1880. I do not claim anything which he describes in his specification; but, 7

Having thus described my invention, what I do claim as new, and desire to secure by Letters Patent, is

1. In a paper-folding machine, the combination, with the lever-arm D, carrying the pastereservoir, of the paste-wheel E, rotated .by a shaft, K, carried by said lever, said shaft being driven from one of the rollers by gears Z), and. means, substantially as set forth, for securing both said paste wheel and reservoir in an inoperative position, substantially as set mechanism, in combination with the adjusting 7 Jonr H.
